Build your AI agent once, then let it answer calls, make calls and reply to chats. Connect it to your SIP trunk, Asterisk or the PBX you already own, and run it self-hosted or on VEXYL Cloud.
The same agent, with the same prompt, tools and knowledge, works across all three channels.
Answer every inbound call from your DIDs, IVR or PBX extensions. Understand the caller, look things up, book, and transfer to a human with context when needed.
Place outbound calls through the API with per-call context, or run reminder, collection and survey campaigns from a CSV with the AI auto-dialer: up to 50 calls at once, retries and result webhooks.
Put the same agent on your website, app or messaging integration through the REST and WebSocket chat API, with streaming replies.
